Entity definition

The IfcMaterialProperties assigns a set of material properties to associated material definitions. The set may be identified by a Name and a Description. The IfcProperty (instantiable subtypes) is used to express the individual material properties by name, description, value and unit.

NOTE  The set of material properties can be assigned to an individual IfcMaterial, a set or composite of materials (IfcMaterialConstituent, IfcMaterialConstituentSet), or set or individual material layer (IfcMaterialLayer, IfcMaterialLayerSet), or a set or individual material profile (IfcMaterialProfile, IfcMaterialProfileSet)
HISTORY  New entity in IFC2x.
IFC4 CHANGE  Entity made non-abstract. The subtypes IfcMechanicalMaterialProperties, IfcThermalMaterialProperties, IfcHygroscopicMaterialProperties, IfcGeneralMaterialProperties, IfcOpticalMaterialProperties, IfcWaterProperties, IfcFuelProperties, IfcProductsOfCombustionProperties, IfcExtendedMaterialProperties have been deleted, use IfcMaterialProperties instead.
